So I installed LinuxMint 13 using a bootable USB . Everything went well except when i removed the bootable USB and restarted my computer, it doesn't boot up. If I plug in the bootable USB and select it as the primary HDD in BIOS the computer boots and goes straight to my LinuxMint install.

hi,i'm glad to see that it worked why that happened in the first place?- when installing from an USB, sometimes, not always, the installer gets confused and places grub in sdb (the USB) instead of sda (the hard drive where it should).

no worriesmy question is: did you copy&paste the above commands exactly as they are in the post (with all the spacings and all the rest?) if you miss a space (or misspell something it will simply not work.

you should have an option in the bios to boot from usb, select that, otherwise the system is going automatically from the usb to the installed system;once you are in the live system (if you open the terminal you have to see mint@mint and not your personal prompt) follow the steps above (copy&paste the output here)

I have had the boot from USB selected since the system wouldn't go straight into Mint on startup. I have two other usb choices in the bios and I have tried both (with my bootable USB connected) and I go straight into redjan.

since we already installed grub in sda (and without errors according to the outputs) there's a couple things you can try:- first and easiest: set the bios to boot from the internal hdd and try again to boot without the usb plugged in

- second (if that one doesn't work): boot as you have been doing until now, remove the usb stick and issue these commands

Hi redjan! The same thing happened to my Dell Inspiron 1525 (replaced Vista with Linux Mint 13). In my case, I used a Plop boot CD to make sure it goes in the live system, resulting in getting the mint@mint prompt at the terminal.
